Methodology & citation

Where these numbers come from#

Sources. HM Land Registry lease records, Companies House filings, local-authority planning applications, EPC records, plus hiring, headcount-growth and news signals. No scraping of private sources.

Model. Every tracked London company is scored 0–100 on the strength, recency and combination of its signals. “In market” means 60+; “imminent” means 80+. Scores re-run weekly; this page rebuilds from the live database after each run — the date above is the date of computation.
